.To all whom 'it may concern:

Be it known that we, Cani. A. .ALEXANDER and ERIC lV. YOUNG, Citizens of the United States, and residents of the city of Tacoma, county of Pierce, and State ot' Washington, have invented certain new and useful Improvements in Wax-Pots, ot' which the tollowing is a specification.

This invention relates to improvements in wax pots, and more particularly to wax pots of that character adapted for use in connection with shoe sewing machines, or machines of like character, wherein liquid wax may be contained and through which the threads used in sewing may be drawn to apply the wax thereto.

It is the principal object of the invention to improve on pots as here betore used, by providing for the waxing of several threads instead of the usual singlethread, and in connection with the wax pot to provide an nimproved tensioning plate which may be ad justed to place a desired tension on the threads drawnthrough the wax and va supple mental spring-like arm 'for taking up slack in the thread between the potand needle while stitching is being done.

In accomplishing these and other objects oi the invention, we have provided the improved details of structure, the preferred :lorms of which are illustrated in the accom panving drawings, wherein-.

Figure l is a perspective view oiE a wax pot constructed according to the present inf vention and equipped with a tensioning plate and spring arm. l

F ig. 2 is a longitudinal sectional view of the same.

Fig. 3 is a transverse sectional view, illustrating the means for attaching the pot to a machine.

Fig. 4 is a ing plate.

Fig. 5 is a detail section view of the tenu sioning plate and bridge between which the threads are drawn.

ln the most common type of wax pot, provision has only been made for two threads at a time, one of which extends to a needle and the other to a bobbin and in such pots when it is desired to use a smaller or larger thread it is necessary to unthread from the pot and then re-thread with the size desired.

In the present device, we have sought to facilitate the work of sewing by providing a pot wherethrough a plurality ot' `threads plan view of the pot and tensionthat 1s being used.

ott different sizes may be kept threaded at all times, and the threads desired may be se lected and used, and when not in use need. not b e unthreaded to make room for the one It is also intended to provide a. single tensioning plate that will take care of all the different threads without unthreading.

In the drawings, '1 designatesawax pot embodying the present invention, and in its preferred construction, comprising an open top receptacle wherein liquid wax may be contained, having parallel front and back walls 2 and 3, respectively, downwardly converging opposite side walls 4, and a bot tom wall 5.

At the base ofthe pot are downwardly and late `ally directed bosses, 7 and 8, each of which is provided with bores 9, opening into the base of the pot and to the outer ends of the bosses, and each bore is equipped with a plug l0. The plugs have squared wrench heads 11, whereby they may be threaded into or from the bores and have holes, or channels 12, therethrough, through which the threads are drawn. y

The pot is preferably attached to the machine with which it is used by means of screw bolts, and 16,` which are extended through the upper and lower ends of the hack wall 2.

l .Extending laterally at one side of the pot. at its upper end, is a flange 18, and mount-1 ed across the same close to the pot wall, is a bridge member consisting of a spring wire 19, having downturned end portions which tit within grooves 21 cut in opposite edges of the flange, to hold the bridge in place. Also mounted on the flange is a tensioning plate 22, of suitable spring metal, having a downturned flange 23 at its outer end and a downwardly pressed transverse rib 24 spaced from the end to seat upon the bridge wire and to space the plate slightly from the flange, and has an upwardly inclined portion 22 which serves as a releasing lever for the tensioningr plate. A bolt 25 extends downwardly through the plate and flange and at its lower end has a thumb nut 26 threaded thereon. which may be tightened or loosened to regulate the pressure of the plate against the bridge.

The plate is also provided between the end flange 23 and rib 24 with a series of openings 28, here shown to he four in numn which is adapted the pot and needle.

Assuming that the pot is so constructed, andthe tensioning plate and take up spring are mounted as described, in using the device, threads indicated at a0, are drawn through the several openings 28 and are passed between the bridge wire 19 and rib 24 of the plate 22, then downwardly through the Openings 12 of' the plugs 10. The thread selected to extend to the needle is then drawn through the eyey of the spring arm 29 and the otherY thread is extended to the bobbing f It is apparent that in this construction, by adjustment of the nutv 26 a desired tension may be maintained on the several threads before they are drawn through the wax and that thejspring arm 29 will act to take up slack in the thread being used.

It will beA seen that such a construction provides for the using of threads of different sizes without rethreading` through the 'pot and much time otherwise lost in rethreading is eliminated.

What we claim as new, is: 1. In combination, a wax pot of the character described having a body portion and a laterally directed flange at its upper edge and having a plurality of base openings, plugs threaded into said openings having longitudinal channelstherethrough through which threads drawn through the pot may be extended, and a tensioningplate fixed to said body flange to maintain tension on the threads.

2. In combination, a wax pot having a plurality of base openings and having a laterally extending flange at an upper edge, plugs, having longitudinal channels therein, threaded into the said base openings, through which threads drawn through the pot may be extended, a transverse bridge secured on the body flange across which threads drawn through the pot are passed and a tension plate secured to the flange and yieldingly urged against said bridge and threads.

3. ln combination, a wax pot having a plurality of base openings and having` a laterally directed flange at its upper edge. a transverse bridge secured on said flange adjacent the edge of the pot, a spring plate having a downpressed, transverse rib adapt ed to seat upon the transverse bridge and having a downturned end engageable with the flange to space the plate from the latter. a bolt extending through the plate between the downturned end and rib, and through the pot flange, adjustable to tension the rib of the plate toward the bridge and against threads that may be drawn between the rib and bridge and through the pot and its base openings.

4. In combination, a wax pot having a plurality of base openings and a laterally directed flange at its. upper edge, said flange having notches in its opposite side adjacent the edge of the pot, a bridge member, com

prising a wire having` down-turned end portion, mounted transversely across said flan ge with said down-turned ends extended into said flange notches, a tensioning plate mounted on the flange having a transverse rib seated upon the bridge to engage threads drawn across the latter and through the pot openings, and having openings through which said threads may be extended to be drawn across the bridge and a screw extended through said plate and pot flange, having a nut adjustable thereon to regulate the tension of the plate against the threads.
